The news was made public as the company gears up to release iOS 4.2.1, which it said will go live later today.

The Find My... facility has to date been part of the Mobile Me, Apple's £59-a-year email and device data syncing service. Find My... allows you to locate your device - assuming, of course, it's connected to the internet - and, if necessary, wipe or lock it remotely.

Anyone who owns an iPhone 4, iPad or fourth-generation iPod Touch can now make use of the service by downloading a free app to a second iDevice, Apple said.

Of course, that's as useful as tits on a bull if you only have one of these iDevices, so we hope Apple will also make the service accessible through the web, as MobileMe is.
